摘　　要：应用异相沉淀法制备聚三苯胺/活性炭复合材料.SEM及电化学测试表明:聚三苯胺与活性炭复合后,材料的粒径从150 nm左右下降到几十nm,该电极具有良好的倍率性能和循环性能,0.5 C倍率放电容量从88.5mAh/g增至105 mAh/g左右,40 C倍率放电容量约达70 mAh/g左右,1000周循环的容量基本不衰减.The PTPAn/active carbon compounds were synthesized by heterogeneous precipitation method.The SEM results show that the size of the PTPAn decreases from about 150 nm to few ten nanometers after being incorporated with active carbon.The PTPAn/active carbon compounds have excellent rate and cycling performance：the discharge capacity increases from 88.5 mAh/g to 105 mAh/g at 0.5 C charge/discharge rate and can reach to 70 mAh/g even at 40 C charge/discharge rate.And the capacity retention of the PTPAn/active carbon compounds remain almost unchanged after 1000 cycles at 40 C charge/discharge rate.
